Check out PGFAGM (Parting Gifts From a Grouchy Man). The point he’s trying to make with those though – is there are no dangerous weapons; Only dangerous people. and security theater does not actually make us safer.

I definitely don’t think the point of this was to make a great gun you’d want to shoot -just prove that all of the rules of the TSA aren’t preventing people from making weapons once past security checkpoints. If someone needs to make a weapon, they will.
